Abstract

The invention provides an operating device of a surge backup protector. The operating device comprises a shell; an electromagnetic release; a push rod reset member; a handle; an operating mechanism which comprises a base frame pivoted on the shell in a resettable manner, a jump pin pivoted on the base frame and matched with the handle in a linkage manner, a lock catch pivoted on the base frame ina resettable manner and matched with the jump pin in a buckling manner, and a transmission rod pivoted on the base frame in a resettable manner, wherein a pushing part for enabling the ejector rod resetting piece to swing towards the ejector rod is arranged on one side, facing the ejector rod resetting piece, of the base frame; a static contact rod assembly which is fixedly arranged on the shell;a movable feeler lever assembly which comprises a movable feeler lever and an opening spring. According to the operating device disclosed in the invention, the base frame is linked with the movable contact rod through the resettable transmission rod, and therefore the movable contact rod is in contact fit with the static contact rod assembly; after the lock catch and the jump pin are slipped and unlocked by the electromagnetic tripper, the base frame enables the ejector rod of the electromagnetic tripper to retract to the original position through the ejector rod resetting piece.

Description

technical field [0001] The invention relates to the field of surge protection equipment, in particular to an operating device for a surge backup protector. Background technique [0002] When the line is invaded by lightning or instantaneous abnormal large current, the surge protector can turn on the shunt in a very short time, so as to avoid the damage of surge to other equipment in the circuit. However, when the surge protector is abnormal or damaged, as the surge backup protector of the surge protector, it can cut off the normal and fault currents and protect the user's electricity safety. The operating mechanism and electromagnetic release are important components of the surge backup protector, and their sensitivity and reliability directly affect the performance of the product. At present, similar products on the market have complex mechanism, troublesome operation and high cost. Contents of the invention [0003] In view of the above-mentioned shortcomings of the pr...
